TECHNICAL FIELD

The present invention relates to hardware for use in the construction of gates and, more specifically, to gate hardware adapted to brace the vertical and horizontal support members of a wooden gate and rotatably connect these members to a fixed structural member.

BACKGROUND OF THE INVENTION

Gates are often used to allow selective access through a wall or fence. Conventionally, gates are constructed as follows. Two vertical support members and two horizontal support members are fastened together in a rectangular shape to form what will be referred to herein as a gate box. Fence boards or the like are fastened to the support members, and one of the vertical support members is rotatably attached by two or more hinge assemblies to a structural member such as a wall or post.

Using conventional gate building techniques, fasteners such as nails or screws are driven through one support member into another support member to form the corners of the gate box. Over time, the force of gravity and wood shrinkage will cause these fasteners to loosen, allowing the gate box to sag out of its desired rectangular shape.

Accordingly, metal L-brackets, wooden brace members, triangular pieces of plywood, and the like are often fastened to the adjacent ends of the support members to strengthen the inside corners of the gate box. In other situations, a wire is placed in tension between the upper proximal and lower distal corners of the gate box to support the lower distal corner of the gate box and thereby reduce sagging of the gate. Such bracing techniques are somewhat effective but also commonly employ fasteners that are susceptible to failure and can be relatively time consuming to implement.

Another problem with conventional gate building techniques is that fasteners such as nails or screws are similarly used to attach the hinge assemblies to the vertical support member adjacent to the structural member. The loads are transferred to the gate through the screws placed in tension. As the wood shrinks and the gate is opened and closed, the fasteners under tension tend to loosen and may eventually fail.

As the hinge fasteners loosen, the entire gate assembly may sag relative to the hinge assemblies and thus the structural member, even if the gate box maintains its rectangular shape. The use of braces at the corners of the gate box will worsen sagging at the hinges because the materials and hardware used for bracing increase the weight of the gate; this increased weight increases the forces of gravity on the fasteners used to attach the hinge assemblies to the proximal vertical support member.

The Applicant is aware of a product sold in Canada as early as approximately 1993 under the tradename “Artistic Steel Gate Frames”. The Artistic Steel Gate Frame product comprises distal and proximal brace members, with hinges being attached to the proximal brace member. A gate assembly constructed using the Artistic product would use upper and lower horizontal wooden support members, but would not use vertical support members. Instead, the distal and proximal brace members would form the structure of the vertical sides of the gate. Accordingly, the brace members of the Artistic product were sold in a plurality of sizes, with each size corresponding to a given distance between the upper and lower horizontal support members.

One problem with the Artistic product is that this system requires the manufacturer to produce and keep in inventory, and the retailer to stock, multiple sizes of brace members.

In addition, the end user is limited to one of these multiple sizes of brace members; one could not create a gate assembly having a custom distance between the upper and lower horizontal support members.

From the foregoing, it should be clear that one object of the present invention is to create bracket systems and methods that are strong, that are easy and inexpensive to use, and which allow significant flexibility in the final design of the gate assembly.

SUMMARY OF THE INVENTION

The present invention is a bracket system or method for forming gate assemblies. The bracket system comprises at least two brace members that are rigidly attached to hinge assemblies. The brace members are adapted to be attached to support members to form two corners of a gate box functioning as the structural portion of the gate assembly. The hinge assemblies are adapted to be rigidly attached to a fence post to allow the gate assembly to pivot relative to the fence post. Gate assemblies of arbitrary height and width can be formed using the bracket system of the present invention

DETAILED DESCRIPTION OF THE INVENTION

Referring initially to FIG. 1, depicted therein is a gate bracket system 20 constructed in accordance with, and embodying, the principles of the present invention. Referring for a moment to FIGS. 2 and 3, the gate bracket system 20 is adapted to form a gate box 22 to be used as part of a gate assembly 24; the gate assembly 24 is in turn to be connected to a structural member such as a fence post 26 (FIG. 3) of a larger structure such as a fence 28.

The exemplary gate assembly 24 comprises in addition to the bracket system 20 distal and proximal vertical support members 30 and 32, upper and lower horizontal support members 34 and 36, and a plurality of fence members 40. The exemplary support members 30-36 are conventional wooden two-by-fours, but other materials and sizes may be used as the support members 30-36. The exemplary fence members 40 are also conventionally made out of wood, but other materials and various sizes of any type of material may be used to form the fence members 40.

The support members 30-36 and fence members 40 do not form a part of the present invention. A description of the construction and operation of these members 30-40 is not necessary to describe how to make and use the present invention and is included herein simply to illustrate the environment in which the present invention operates.

The fence post 26 is conventionally a wooden four-by-four, but other materials and sizes may be used to form the structural member to which the gate assembly 24 is rotatably attached. For example, rather than a fence post 26, the structural member may be a wall of a structure. The fence post 26 and fence 28 also are or may be conventional and are not part of the present invention. As with the support and fence members 30-40 introduced above, a description of the construction and operation of the post 26 and fence 28 is not necessary to describe how to make and use the present invention. The fence post 26 and fence 28 are described herein simply to illustrate the environment in which the present invention operates.

The gate bracket system 20 of the present invention comprises first and second distal brace members 50 and 52 and first and second brace assemblies 54 and 56. The first brace assembly 54 in turn comprises a first proximal brace member 60 and a first hinge assembly 62, while the second brace assembly comprises a second proximal brace member 64 and a second hinge assembly 66.

The exemplary brace members 50, 52, 60, and 64 each comprise a horizontal portion 70, a vertical portion 72, and a brace portion 74. An outer end 72 a of the vertical portions 72 is rigidly connected to an attachment region 70 a of the horizontal portions 70. The exemplary brace portion 74 is preferably rigidly connected at an angle between bracing regions 70 b and 72 b of the horizontal and vertical portions 70 and 72, respectively.

The choice of materials and shapes of the materials are not essential to any particular implementation of the present invention. The primary requirements of the brace members 50, 52, 60, and 64 are that these members each define a horizontal support surface 80 and a vertical support surface 82 such that these surfaces rigidly extend from each other at a right angle. In the exemplary system 20, the horizontal support surfaces 80 are formed on the horizontal portions 70 and the vertical support surfaces 82 are formed on the vertical portions 72.

A plurality of fastener holes 90 are formed in the brace members 50, 52, 60, and 64; the fastener holes 90 are adapted to allow fasteners 92 to attach, in a conventional manner, the brace members 50, 52, 60, and 64 to the support members 30-36. The fasteners 92 are preferably self-tapping screws but can be nails, bolts, or the like. The fasteners 92 are not part of the gate bracket system 20 of the present invention per se but, as will be described in further detail below, are used to combine the bracket system 20 with the support members 30-36 to form the gate assembly 24.

The exact number and location of the fastener holes 90 is not critical to any given implementation of the present invention. In a broadest form of the bracket system 20, the fastener holes 90 can be formed anywhere along the horizontal portions 70 and vertical portions 72. The only requirement for the number and spacing of these holes is that the fasteners 92 extend through these holes 90 and into the support members to rigidly secure the brace members to the support members.

Given the foregoing general understanding of the present invention, the distal bracket members 50 and 52 and the proximal bracket assemblies 54 and 56 of the present invention will now be described in further detail with reference to FIGS. 4-11.

The attachment and bracing regions 70 a and 70 b of the horizontal portions 70 of the exemplary bracket members 50, 52, 60, and 64 are formed located generally as follows.

The horizontal portions 70 have an outer end 70 c and an inner end 70 d. The exemplary attachment regions 70 a are located between approximately 15-30%, and preferably approximately 20%, of the distance between the horizontal portion ends 70 c and 70 d as measured from the outer ends 70 c. The bracing regions 70 b are located between approximately 80-95%, and preferably approximately 88%, of the distance between the horizontal portion ends 70 c and 70 d as measured from the outer ends 70 c.

The horizontal portions 70 further define spacing regions 70 e (between the attachment regions 70 a and the outer ends 70 c), inner regions 70 f (between the bracing regions 70 b and the inner ends 70 d), and intermediate regions 70 g (between the attachment regions 70 a and the bracing regions 70 b).

The length of the spacing regions 70 e is determined such that the vertical support members 34 and 36 fit snugly between the vertical portions 72 and the outer ends 70 c. In the case of the proximal bracket assemblies 54 and 56, the length of the spacing regions 70 e allows the vertical support members 34 and 36 to fit snugly between the vertical portions 72 of the third and fourth bracket members 60 and 64 and the first and second hinge assemblies 62 and 66, respectively. When, as is typical, two-by-four dimensional lumber is used to form the vertical support members, the length of the spacing regions 70 e will be approximately 3 1/2″, or slightly greater to allow for variations in the true dimensions of the lumber.

The vertical portions 72 each comprise the outer ends 72 a discussed above and an inner end 72 c. The bracing regions 72 b are located approximately 85% of the distance between the horizontal portion ends 72 a and 72 c as measured from the outer ends 72 a. The vertical portions 72 thus each define a main region 72 d between the outer end 72 a and the bracing region 72 b and an inner end region 72 e between the bracing region 72 b and the inner end 72 c.

In the horizontal portions 70 of the exemplary brace members 50, 52, 60, and 64, first, second, and third fastener holes 90 a, 90 b, and 90 c are formed in the spacing regions 70 e, inner regions 70 f, and intermediate regions 70 g, respectively. The first, second, and third fastener holes are spaced approximately 15%, 46%, and 96%, respectively, of the distance between the horizontal portion ends 70 c and 70 d as measured from the outer ends 70 c.

In the vertical portions 72 of the exemplary brace members 50, 52, 60, and 64, fourth and fifth fastener holes 90 d and 90 e are formed in the main region 72 d and a sixth fastener hole 90 f is formed in the inner end region 72 e. The fourth, fifth, and sixth fastener holes 90 d, 90 e, and 90 f are spaced approximately 15%, 46%, and 96% of the distance between the horizontal portion ends 72 a and 72 c as measured from the outer ends 72 a.

The fastener holes 90 of the exemplary brace members 50, 52, 60, and 64 are formed along a horizontal center line A of the horizontal portion 70 and a vertical center line B of the vertical portion 72.

The exemplary horizontal and vertical portions 70 and 72 are made of flat pieces of rigid metal, but other relatively rigid materials and shapes that function in a similar manner may be used. For ease of manufacturing, the exemplary horizontal and vertical portions 70 and 72 are identical in length, and the fastener holes 90 are formed at identical locations therein; only one part thus needs to be fabricated and stocked to form the exemplary brace members 50, 52, 60, and 64.

The brace portion 74 is typically round or flat metal stock, but other shapes and materials may be used. For example, the brace portion 74 may be a triangular web of flat material that extends between the horizontal and vertical portions 70 and 72. In this case, the entire brace member may be cast of metal or injection molded from plastic. If a triangular web or similar brace portion is used, it may be necessary to form the fastener holes 90 such that they are offset from the horizontal and vertical centerlines A and B.

From the foregoing, it should be clear that the exemplary brace members 50, 52, 60, and 64 are identical, which is preferred for manufacturing purposes. However, these brace members 50, 52, 60, and 64 need not be identical to practice the present invention in its broadest form.

The first and second hinge assemblies 54 and 56 are or may be conventional and will be described herein only to the extent necessary for a complete understanding of the present invention.

As is conventional, the hinge assemblies 54 and 56 each comprise a gate plate 120 and a post plate 122. These plates define hinge projections 124 that receive a hinge pin (not shown). The hinge pin allows the gate and post plates 120 and 122 to rotate relative to each other about a hinge axes C and D defined by the hinge assemblies 54 and 56.

The outer ends 70 c of the horizontal portions 70 of the first and second brace members 60 and 64 are rigidly connected to the gate plates 120. In particular, the horizontal center lines A of the horizontal portions 70 of these brace members 60 and 64 are tangential to circles centered about the hinge axes C and D, respectively. The vertical center lines B of the vertical portions of the brace members 60 and 64 are parallel to the hinge axes C and D, respectively.

An array of fastener holes 90 is formed in the post plate 122 to allow this plate to be rigidly attached to the fence post 26. Preferably four fastener holes 90 are formed in the post plate 122. The drawing depicts fastener holes 90 in the gate plate 120; these holes 90 in the plate 120 need not be used, but will be present if off-the-shelf hinge assemblies 62 and 66 are used.

The process of combining the bracket system 20 with the support members 30-36 to form the gate box 22 will now be described with reference to FIG. 2.

Initially, as is conventional, the support members 30-36 are cut to the desired lengths. The length vertical support members 30 and 32 generally correspond to the height of the gate assembly 24, while the length of the horizontal support members 34 and 36 closely correspond to the width of the gate assembly 24. The minimum lengths of the support members 30-36 are determined by the horizontal portions 70 and vertical portions 72 of the brace members 50, 52, 60, and 64; in particular, the support members 30-36 must be at least twice as long as the lengths of the horizontal and vertical portions 70 and 72 to prevent overlapping of the horizontal portions 70 or vertical portions 72 of adjacent brace members.

The first and second distal brace members 50 and 52 and first and second brace assemblies 54 and 56 are arranged such that: (a) horizontal and vertical support surfaces 80 a and 82 a of the first distal brace member 50 define first and second support surfaces of the bracket system 20; (b) horizontal and vertical support surfaces 80 b and 82 b of the second distal brace member 50 define third and fourth support surfaces of the bracket system 20; (c) horizontal and vertical support surfaces 80 c and 82 c of the first proximal brace member 60 define third and fourth support surfaces of the bracket system 20; and (d) horizontal and vertical support surfaces 80 d and 82 d of the second proximal brace member 54 define third and fourth support surfaces of the bracket system 20.

The fasteners 92 are then inserted through the fastener holes 90 of the brace members 50, 52, 60, and 64 and into the support members 30-36 to form the gate box 22. In particular, fasteners 92 are driven through the holes 90 and into the support members 30-36 such that: (a) the upper horizontal support member 30 is drawn tight against the first and fifth support surfaces defined by the first distal brace member 50 and second proximal brace member 60; (b) the lower horizontal support member 32 is drawn tight against the second and sixth support surfaces defined by the second distal brace member 52 and fourth proximal brace member 64; (c) the distal vertical support member 34 is drawn tight against the third and fourth support surfaces defined by the first and second distal brace members 50 and 52; and (d) the proximal vertical support member 36 is drawn tight against the seventh and eight support surfaces defined by the first and second proximal brace members 60 and 64.

The exact order of the attachments described in the preceding paragraph is not critical to the present invention in its broadest form. However, with the brace members 50, 52, 60, and 64 described herein, fasteners 92 are preferably driven through at least the first fastener holes 90 a formed in the spacing regions 70 e of the horizontal portions 70 before fasteners 92 are driven through the fastener fourth, fifth, or sixth fastener holes 90 d-e of the vertical portions 72. Otherwise, the vertical support members 34 and 36 may block access to the first fastener holes 90 a. Preferably, fasteners 92 are driven through the first through third fastener holes 90 a-c before fasteners are driven through the fifth through sixth fastener holes 90 d-e.

With the gate box 22 formed as described above, the hinge axes C and D will be substantially aligned. The gate box 22 so formed may thus then be attached to the fence post 26 by fasteners 92 extending through the fastener holes 90 in the post plate 122 and into the post 26. When the post plates 122 are rigidly connected to the post 26, the gate box 22 pivots relative to the fence post 26 about the hinge axes C and D.

The gate assembly 24 may be formed before or after the gate box 22 is attached to the fence post 26 by attaching the fence members 40 to at least one, and preferably at least two, of the support members 30-36 of the gate box 22.

Given the foregoing, it should be clear that the present invention may be embodied in forms other than those depicted and described herein. The scope of the present invention should thus be determined by the claims appended hereto and not the preceding detailed description of the preferred embodiment.
